While jazzy Cheek To Cheek sweethearts Lady Gaga and Tony Bennett surely come as no surprise as headliners, the list also includes Pitbull (dale!), Ed Sheeran, T.I. and No Doubt. Kind of a loose definition of jazz, no? That is, unless Pitbull will be serving up jazzy renditions of “Hotel Room Service” and “Fireball,” in which case…we’re already on a plane right now.

Check out the full roster in the announcement video after the jump, which also includes Elton John, The Who, Keith Urban, Hozier, Big Freedia, Estelle, John Legend, Kacey Musgraves and Paloma Faith. Will you be attending?
